And the air pressure detection module 11 is used for detecting air pressure change in the smoking cavity and generating a first detection signal. It should be noted that the air pressure change in this embodiment refers to a change of the air pressure in the smoking cavity relative to a preset ambient air pressure, where the ambient air pressure may be atmospheric pressure or may be an air pressure in a preset vacuum environment, and whether to start the airflow detection module is determined by detecting a change of the air pressure in the smoking cavity relative to the ambient air pressure.
And the airflow detection module 12 is used for detecting the intake airflow of the smoking cavity after the starting, and generating a second detection signal. It should be noted that, in this embodiment, the airflow detection module 12 and the air pressure detection module 11 are two independent modules, that is, the two detection modules are separately disposed, so that when a single detection module fails, the failure detection module can be detached and maintained without detaching the whole detection module, thereby reducing the maintenance difficulty. The term "independent" in this embodiment means that the detection functions of the two detection modules are implemented by respective corresponding structures, the two detection modules may be integrated on one chip by an MEMS process, or may be respectively disposed on two chips, and the two detection modules independently implement their respective detection functions no matter they are integrated on one chip or disposed on two chips respectively.
And an atomization module 13 for generating the smoke by atomization.
And the control module 14 is configured to control to start the airflow detection module 12 when it is determined that the air pressure variation value in the smoking cavity is greater than or equal to a preset air pressure variation threshold according to the first detection signal, and is configured to control the amount of smoke atomized by the atomization module 13 in unit time according to the second detection signal.
In the implementation process, the detection result through the air pressure detection module 11 controls the starting of the air flow detection module 12, then the air inlet flow of the smoking cavity detected by the air flow detection module 12 controls the atomized smoke flow of the atomization module 13 in unit time, and because the air inlet flow of the smoking cavity is related to suction, the atomization device provided by the embodiment of the application can automatically control the atomized smoke flow of the atomization module 13 in unit time according to the size of the suction, so that the atomization device is more intelligent, and the satisfaction degree of user experience is improved. In addition, control module just controls when confirming the atmospheric pressure change value in the smoking cavity more than or equal to and predetermines atmospheric pressure change threshold value and starts airflow detection module, promptly, airflow detection module need not be in operating condition for a long time, has reduced atomizing device's whole power consumption, and the atomizing device that this application provided has low-power consumption concurrently can stand by for a long time and the advantage of high accuracy atomization volume control.
It should be noted that the airflow detection module 12 and the air pressure detection module 11 in the embodiment of the present application may be disposed at any position in the smoking cavity as long as the intake airflow and the air pressure change in the smoking cavity can be detected. Preferably, as shown in fig. 2, the airflow detecting module 12 and the air pressure detecting module 11 are disposed at an air inlet of the smoking cavity, so that the airflow detecting module 12 can more accurately detect the flow rate of the intake air at the air inlet, and the air pressure detecting module 11 can more accurately detect the air pressure change at the air inlet. Preferably, the atomization module 13 in the embodiment of the present application is disposed at an end close to the suction port, and the smoke atomized by the atomization module 13 enters the smoking cavity, mixes with the gas in the smoking cavity, and then is output through the gas outlet of the smoking cavity.
In the embodiment of the present application, the types of the sensors that implement the detection function in the air pressure detection module 11 and the air flow detection module 12 may be arbitrarily selected by a developer. For example, the air pressure detection module 11 detects a change in air pressure using the thermal gas flow rate-based flow sensor, and the air flow detection module 12 detects an intake air flow rate using a pressure difference sensor based on a change in pressure. Preferably, the air pressure detecting module 11 in the embodiment of the present application includes a differential pressure sensor for performing differential pressure detection based on pressure change, and the air flow detecting module 12 includes a flow sensor for performing air flow detection based on thermal type air flow. The pressure difference sensor based on pressure change carries out pressure difference detection's pressure loss is lower, and the flow sensor based on hot type gas flow carries out air current detection's detection precision is higher, and from this, the atomizing device that this application embodiment provided has concurrently low-power consumption can stand by for a long time and the advantage of high accuracy atomizing control.
It is understood that the differential pressure sensor in the embodiments of the present application may include a piezoresistive conversion unit for converting a detected pressure change signal in the smoking cavity into a first resistance change signal, and a first resistance-voltage conversion unit for converting the first resistance change signal into a first voltage signal. The measuring end of the piezoresistive conversion unit in the embodiment of the application can be connected with the air inlet of the smoking cavity so as to convert a pressure change signal at the air inlet in the smoking cavity into a first resistance change signal. Alternatively, the piezoresistive conversion unit may be implemented by a piezoresistive switch mechanical structure, which may reduce power consumption. In the implementation process, the piezoresistive differential pressure sensor is adopted to convert the detected pressure change signal into a first resistance change signal, and then the first resistance change signal is converted into a first voltage signal, so that the detection sensitivity is high, and the power consumption is low. Of course, in other embodiments, other types of differential pressure sensors may be used.

In this embodiment, the signal output by the comparator 112 is also the first detection signal mentioned above, and the control module 14 can determine whether the air pressure variation value in the smoking cavity is greater than or equal to the preset air pressure variation threshold according to the first detection signal. For example, when the first detection signal output by the comparator 112 is a high level signal, the control module 14 may determine that the air pressure variation value in the smoking cavity is greater than or equal to the preset air pressure variation threshold according to the high level signal, and when the first detection signal output by the comparator 112 is a low level signal, the control module 14 may determine that the air pressure variation value in the smoking cavity is smaller than the preset air pressure variation threshold according to the low level signal. It should be noted that, the air pressure change threshold in this embodiment may be flexibly set by a developer, the air flow detection module 12 is turned on when it is determined that the air pressure change value in the smoking cavity is greater than or equal to the preset air pressure change threshold, and the air pressure detection module 11 is turned off when it is determined that the air pressure change value in the smoking cavity is smaller than the preset air pressure change threshold, so as to prevent the air flow detection module 12 from being turned on by mistake, and reduce unnecessary energy waste.
Referring to fig. 4, in another embodiment, the air pressure detecting module 11 includes a differential pressure sensor 111, a first amplifying unit 113 and a first analog-to-digital converting unit 114, where the first amplifying unit 113 is configured to amplify the first voltage signal to obtain a first voltage amplified signal, and the first analog-to-digital converting unit 114 is configured to perform an analog-to-digital conversion on the first voltage amplified signal to obtain a first detection signal, and at this time, the first detection signal represents an air pressure change in the smoking cavity, so that the control module 14 can directly determine whether the air pressure change value in the smoking cavity is greater than or equal to a preset air pressure change threshold according to the first detection signal and the preset air pressure change threshold.

The measuring end of the thermal resistance conversion unit in the embodiment of the application can be communicated with the air inlet of the smoking cavity, so that a heat flow temperature change signal at the air inlet in the smoking cavity is converted into a first resistance change signal. Of course, in other embodiments, other types of flow sensors may be used.
Referring to fig. 5, the airflow detecting module 12 includes a flow sensor 121, a second amplifying unit 122, and a second analog-to-digital converting unit 123, wherein the flow sensor 121 may include the thermal resistance converting unit and the second resistance-to-voltage converting unit described above, and may also include other types of converting units. The second amplifying unit 122 is configured to amplify the second voltage signal to obtain a second voltage amplified signal, and the second analog-to-digital converting unit 123 is configured to perform analog-to-digital conversion on the second voltage amplified signal to obtain the second detection signal. The second analog-to-digital conversion unit 123 may output the second detection signal of N bits and send the second detection signal to the control module 14. Referring to fig. 6, the control module 14 can control the amount of smoke atomized by the atomizing module 13 in unit time to be proportional to the amount of intake air of the smoking cavity according to the second detection signal, so as to better meet the user requirement and improve the satisfaction degree of user experience.
It should be noted that, in the embodiment of the present application, the atomizing module 13 includes a heating unit for heating the liquid to be atomized, and in an implementation manner, the control module 14 is configured to control a heating power of the heating unit for heating the liquid to be atomized according to the second detection signal, so as to control an amount of the mist atomized in unit time. In other embodiments, the control module 14 may control the liquid to be atomized for atomizing per unit time.
In some embodiments, after the airflow detecting module 12 is started, the control module 14 may further control to turn off the atomization function of the airflow detecting module 12 and the atomization module 13 when it is determined that the intake flow value in the smoking cavity is less than or equal to the preset intake flow threshold according to the second detection signal, or may control the airflow detecting module 12 and the atomization module 13 to enter a low-power-consumption sleep state, so as to reduce energy consumption. When the air pressure detection module 11 detects that the air pressure change value in the smoking cavity is greater than or equal to the preset air pressure change threshold, the air flow detection module 12 may be awakened again.
The atomization device provided by the embodiment of the application may further include a battery, and the control module 14 is configured to, after controlling to start the airflow detection module 12, control to shut down the atomization functions of the airflow detection module 12 and the atomization module 13 if it is determined that the operating voltage of the battery is smaller than the first preset operating voltage threshold. The first preset operating voltage threshold may be an operating voltage of the battery when the airflow detecting module 12 and the atomizing module 13 of the atomizing device can operate normally, for example, the first preset operating voltage threshold may be set to 3V.
It should be further noted that the atomization device may further include a charging module for charging the battery, and the control module 14 is further configured to control the charging module to perform trickle charging on the battery when the working voltage of the battery is less than a second preset working voltage threshold, control the charging module to perform constant current charging on the battery when the working voltage of the battery is greater than or equal to the second preset working voltage threshold and is less than a third preset working voltage threshold, and control the charging module to disconnect the connection between the charging module and the battery when the working voltage of the battery is greater than or equal to the third preset working voltage threshold. In the charging process, trickle low current charging is adopted firstly when the voltage of the battery is lower so as to protect the battery, the damage to the internal structure of the battery caused by large current impact is avoided, constant current charging is adopted when the voltage of the battery reaches a safe range, the charging efficiency is improved, and when the voltage of the battery reaches a normal working voltage, disconnection charging is controlled, so that the damage to the battery caused by overcharging is avoided.
